Letters Patent No. 98,067, dated December 2l, 1869.

The Schedule refened to in 'fuese Letters Patent and making part of thesame.

*Mov- Y To all whom it may concern:

Be it known that I, A. C. J UDsoN, of Grand Rapids, in the county ofWood, and State of Ohio, have invented a new and improved Inmp; and I dohereby declare that the following is a full, clear, and exactdescription thereof', which will enable others skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming part of' this specification.

This invention relates to improvements in pumps, such as are commonlyused for lifting water from wells, and has for its object to provide animproved construction and arrangement of valves for the same;

also an improved arrangement of operating-devices.` A

The invention consists in an arrangement ot' two metal dish-shapeddisks, with a diaphragm of leather between them, and another leatherdiaphragm above, adapted for the better support oi' the water inlifting.

It also consists in an arrangement for operating the pump-rod withoutlateral Vibration, so that itV may be packed tightly in the tube, toprevent foul matter and vermin from getting in.

Figure 1 represents an elevation of my improved pump, partly in section;

Figure 2 represents a front elevation;

Figure 3 represents a section of the valve; and

Figure 4 represents a plan View ot the same.

Similar letters oi' reference indicate corresponding parts.

A represents one metallic disk, which is concave on the upper surface,and provided with notches B. in the edge, for the passage ot' the water.

Above it is placed a leather diaphragm, C, with corresponding holes forthe passage of the water.

Above this is placed another disk, D, which is bevelled on the lowerside, to permit the necessary vibration of the diaphragm C. vThis diskis also provided with holes or notches, for the passage oi the water, l,and is concave on the top.-

Above it another leather liliaphragm,-E, is placed,

but without holes.

themetallic disks to prevent them Ifrom rubbing on the surface of thetube. v

Above the cylinder G, where the valve works, I prefer to reduce the sizeof the' pump-tube, for economy of construction, and to make it moreconvenient to handle.

In .order to work the rod II without .lateral vibrte tion, so that itmay be packed at the top, as represented at I, I introduce, between thehandle ory connectingrod'K, operatedby it, a bent arm, L, arranged towork vertically, in suitable guides, and to this I conneet the pump-rod,as shown at M, whereby it is caused to move up and down in right lines,enabling me to make use ot' the packing I, with great advantage', iu

protecting the pump from foul mattei', vermin, &,c.

Having thus desclibed my invention, I claim as new, and desire to secureby. Letters Patent- The improved lifting-pump valve, comprising the twometal disks, A D, and diaphragme E, Ste., all arranged and applied tothe pump-rod, as specilied.
